This is the 2nd My Little Pony Equestria Girls movie. If you are a fan you will probably like this and know what it is about but if not I will explain.
First off you got to know for the most part the movie doesn't take place in the Pony world but rather an alternative dimension that has human versions of all the Pony characters. Twilight Sparkle the pony once again uses a portal to travel to the human world to help out the human versions of her pony friends. 3 new evil girls who are actually sirens have shown up at the canterlot high and Twilight, Rainbow Dash and friends must find a way to stop them from taking over the school and making everyone fight with eachother.
Through a lot of songs, and a battle of a bands much fun is had.
Movie was great as were the songs, only thing I would knock it for is, I wish we saw more of the actual ponies in the movie because part of the fun of My Little Pony is that they are ponies, which we only get about like 5 min of ponies, the rest is the human version.
If you are a brony or have kids this is a great movie to buy.
